2.2.8 버전으로 낮췄을 때는 이렇게 오류가 나면서 스프링이 종료가 되는데, 2.3.0 버전 이후에는 오류가 발생하지 않습니다.

혹시 이 문제를 해결할 수 있는 방법이 있을까요?

제가 의심한 문제는 spring 자체적인 변경점이 있거나, hibernate에서 변경점이 있는 것인데... 찾기가 쉽지 않네요.

https://mvnrepository.com/artifact/org.springframework.data/spring-data-jpa/2.3.0.RELEASE

문제점을 버전을 내려서 확인하고 소스는 정상동작 하는 상태입니다. 졸면서 하다가 ㅠㅠ 엉뚱한데에 소스를 넣었었네요.
